A continuous discharge from the relief valve vent indicates what?

A continuous discharge from the relief valve vent indicates that the assembly needs to be repaired. In a properly functioning backflow prevention assembly, the relief valve is designed to open only when there is an excess of pressure in the system, allowing the system to relieve that pressure safely. If there is a continuous discharge, it typically means that the relief valve is either malfunctioning or there is an ongoing issue within the assembly that is causing it to remain open. This condition is not normal operation and signifies a need for repair to ensure the backflow preventer functions correctly and the system remains safe and effective. Regular maintenance and prompt attention to such discharge are crucial to prevent contamination and ensure compliance with safety standards.
